In 2005, Dave Chappelle abruptly walked away from his popular sketch comedy series and turned up in South Africa. Chappelle, who during a June 2004 standup performance had complained the show was "ruining my life," later said that he was unhappy with the direction the show had taken. In July 2010, a private plane was forced to land after Chappelle was deemed a safety risk after he reportedly refused to fasten his seat belt, made repeated visits to the cockpit and grabbed the pilot's arm.
